If you are using n8n cloud there is not really anything you could do it is something we would have to do however we don’t block any outbound traffic so there is no reason for it to not make it through.
I know we have had issues with some hosts in the past like IONOS who block user agents with less than 4 characters which causes issues as we use n8n it could be a general Azure issue but I can’t see anything for that on the status pages.
